Patent DE-3710328-A1 (DE)
Title: Fixed bed rotary tube reactor
Inventor: SOEDER CARL-JOHANNES PROF
IPC: C12M1/10
Filed: 1987-03-28
Abstract: In a generally horizontal (in particular slightly inclined) rotary tube reactor operating with continuous flow of the medium to be treated and having a dumped packing leaving 10 to 30% free space, which rotary tube reactor is continuously or intermittently set in rotating or rocking motion about its longitudinal axis, the utilisation of the medium (liquid or gas) supplied can be intensified if, of the axially parallel feed tubes which have corresponding perforations, are provided along the interior wall and are distributed over the periphery, in each case only some, in particular the tubes passing through the region beneath the rotary tube axis, are impinged with medium to be supplied. A matched ring distributor having a stationary slit diaphragm serves, in particular, for this purpose.
Patent DE-3711880-A1 (DE)
Title: Solid-state image sensor
Inventor: YAMAWAKI MASAO
IPC: H04N5/341
Filed: 1987-04-08
Abstract: A so-called narrow-channel effect causes various potential wells in transmission channels. A solid-state image sensor is to be provided in which the potential is uniform so that no charges are trapped. An impurity region (33) for forming a transmission channel (3) of a vertical charge-coupled device (CCD) has a side wall which is in contact, over its entire length, with an impurity region (40) for controlling a charge transfer threshold voltage Vth. A deep section can thus be prevented from forming in a potential well as a result of the so-called narrow-channel effect. Such image sensors can be used in electronic cameras. <IMAGE>
Patent DE-3713068-A1 (DE)
Title: Method and arrangement for converting overlapping input events to time-serial form, for several registers in devices of data processing systems
Inventor: BRAEUER GERALD
IPC: G06F12/0855
Filed: 1987-04-16
Abstract: For registers which can be connected both to individual data sources (IOP) and to a common data source (CPU/SVP), and for which only one control connection for common switching of all the registers is available for switching to the common data source, the control signal (TF) which causes the switching is linked to two successive control cycle pulses (CLA and CLB), with a time separation between them, of which only one causes the switching and the acceptance of the data of the common data source (CPU/SVP) into the selected register (EW). If the first control cycle pulse (CLA) coincides with a request from the individual data source (IOP), the latter is handled first, and only the second control cycle pulse (CLB) is effective. Otherwise, the first control cycle pulse (CLA) is always effective, and a subsequently incoming request (I.STROBE) from the individual data source (IOP) is only executed after the end of the first control cycle pulse (CLA). <IMAGE>

Title: Sensor for a safety device for motor vehicles
Inventor: RUEGER BERNHARD
IPC: B60R21/01
Filed: 1987-05-14
Abstract: In a sensor for a safety device for motor vehicles, which is arranged in or directly behind the outer skin of the motor vehicle, two deformation signal elements are located at a small distance one behind the other, the said elements supplying a signal in the event of a deformation of predetermined severity. The said signal is fed to an evaluation circuit, for example in the form of a time-window comparator which effectively distinguishes the operation case in which the triggering of the safety device is required from other operating cases in which it may be possible that both deformation signal elements supply a signal but this is not sufficent for the specified conditions. Such a case occurs for example if, on installing the sensor in a door, this door is closed violently or an obstacle penetrates the passenger compartment of the vehicle relatively slowly.

Patent DE-3735918-A1 (DE)
Title: Flap system
Inventor: SINDERMANN HARRY
IPC: B64C29/00
Filed: 1987-10-23
Abstract: A fan is stationed horizontally at the centre point of an aircraft. During take-off, masses of air are sucked in through the fan, which masses of air initiate the vertical take-off by means of an opened flap system in the fuselage base. Once the desired take-off altitude is reached, the flap system is closed and the masses of air which are in consequence deflected are moved through a fuselage which tapers towards the rear where, at the end, three nozzles of variable diameter provide the thrust. Two further nozzles are fitted on the right and left in the side of the aircraft. They are supplied with air tapped off the fan, likewise have an adjustable diameter, are intended to compensate for rolling movements and are intended to be used for control about the vertical axis.

Title: Hydraulic brake system
Inventor: SCHONLAU JUERGEN
IPC: B60T13/24
Filed: 1988-01-12
Abstract: A hydraulic brake system for motor vehicles is proposed. The system comprises a master cylinder (18), wheel cylinders, a pneumatic brake booster (2) and a control module (6) for generating a pneumatic pressure differential for the pneumatic brake booster. In addition to the pneumatic brake booster, a hydraulic brake booster is provided, which is incorporated in the master cylinder (18) and is acted upon by a hydraulic booster pressure, which is generated by the pneumatic brake booster (2). A reaction force transmission element (43) is provided, which senses the pressure in the booster chamber (15) and converts it into a reaction force which can be felt by the driver on the brake pedal (24) during the braking sequence. The master cylinder, hydraulic brake booster, the device for generating a reaction force and the pneumatic control module are designed as one assembly (1), whilst the pneumatic brake booster is arranged separately. The invention permits great flexibility when fitting the system in motor vehicles of different types. An improvement of the reaction force on the brake pedal is also achieved by means of the invention. <IMAGE>
Patent DE-3805542-A1 (DE)
Title: Device for drip-free ladling
Inventor: ZIMMERLI ANDREAS
IPC: A47G21/14
Filed: 1988-02-23
Abstract: A wiping-off plate (1) equipped with at least one drainage opening (2) is arranged at the edge of a vessel containing a viscous liquid capable of dripping, e.g. a thick sauce. It is either firmly connected to the edge of the vessel or can be attached to this edge with the aid of supporting strips (3, 6). When ladling the viscous material out of the vessel, the lower part of the ladle is passed over the surface of the wiping-off plate (1) and is thus cleaned. The wiped-off material drips back into the vessel. The advantage of this device lies in the fact that the ladled material is handled economically and in that the surrounding area of the vessel is not dirtied by the drips of the viscous liquid. When using the device in the kitchen, a worker occupied with the cleaning of the plate edges can be dispensed with. The amount of kitchen linen used is reduced and an appetising, hygienic impression for the guest is achieved. <IMAGE>

Title: Method and device for drying a fluid layer applied to a moving carrier material
Inventor: DURST FRANZ PROF DR
IPC: F26B21/12
Filed: 1988-05-13
Abstract: A device for drying a fluid layer applied to a carrier material moving through a drying zone, the layer containing evaporable solvent components and non-evaporable components, comprises a drying device (1) with a drying channel (2), through which the carrier material band (4) runs in the longitudinal direction, to which the fluid layer to be dried is applied. The drying channels has a gas-/air permeable channel top surface (7), through which a gas stream, in particular a heated airstream, flows into the drying channel. The channel top surface (7) is inclined with respect to the horizontally running channel base surface (3). Adjoining the drying channel (2) is a gas exchange chamber (15) which contains a fan (12), the fan outlet (16) of which is directed towards a heat exchanger in a dividing wall (10) between the gas exchange chamber (15) and a drying space (5) situated above the drying channel (2). The gas exchange chamber (15) contains a throttle device (13 and 14, respectively) in its bottom surface (18) and in its upper gas inlet (19). The drying device (1) furthermore contains a suction fan (9) which is arranged above the top surface of a through-flow channel (20) and is connected to the through-flow channel via a suction orifice. A throttle device (8) is likewise situated in the outlet (11) of the suction fan (9). <IMAGE>
Patent DE-3816567-A1 (DE)
Inventor: WALTER MARTIN
IPC: B06B1/06
Filed: 1988-05-14
Abstract: For the purpose of inducing ultrasonic oscillations in a liquid in a container, ultrasonic oscillators are fixed on the outside of the wall serving as a membrane. Due to localised cavitation erosion this wall becomes untight, which leads to the destruction of the entire device. In order to prevent this it is proposed to attach a mounting ring on the ultrasonic oscillator near to the oscillation node, which mounting ring permits the ultrasonic oscillator to be inserted into the container so that it acts directly on the liquid with its sound-emitting cone, it being possible for the end faces of the sound-emitting cones to dip into the liquid at a distance of lambda/4 for the purpose of completely irradiating the liquid acoustically. <IMAGE>

Title: Current interrupter with an arc bounding device
Inventor: NACHTIGALL KLAUS-PETER DIPL IN
IPC: H01H9/46
Filed: 1988-06-03
Abstract: The invention relates to a current interrupter with an arc bounding device, consisting of a stationary contact and of a moving contact arm, which are provided with contact pieces. Arc extinguishing plates are arranged transversely with respect to the movement direction of the moving contact arm, into which arc extinguishing plates the arc is guided via an arc running rail. In this case, it is advantageous for the transfer of the arc from the contacts onto the running rail if the running rail is composed partially or entirely of a material having a low electrical work function. The use of magnesium or magnesium alloys, as well as rare-earth materials, is particularly advantageous. The arc running rail (5) is advantageously composed of ferromagnetic steel, while a strip (6) of small width and composed of a material having a low electrical work function runs in the longitudinal direction of the arc running rail, from the contact piece to the end of the arc running rail. <IMAGE>
Patent DE-3823975-A1 (DE)
Inventor: RUNTSCH ERHARD
IPC: H01H71/10
Filed: 1988-07-15
Abstract: Selective automatic main circuit-breaker In known selective automatic main circuit-breakers, the disconnection point in the main current path is periodically closed, resulting in higher I<2>t let-through values given a short-circuit current disconnection in a given short-circuit current range. This problem is remedied, in that, after the first short-circuit pulse has been limited, the re-closing of the main contact point is carried out only given nominal operating conditions, and is time-controlled by a selectivity device (33) located in a shunt current path connected in parallel with the main current path. Preferred application area of the novel selective automatic main circuit-breaker are low-voltage distribution systems, especially building installations. <IMAGE>

Title: Process for the non-contact, eruptive removal of sediment and other deposits
Inventor: BOEHRINGER VOLKER ULRICH
IPC: B08B3/12
Filed: 1988-12-02
Abstract: Process for the non-contact, eruptive removal of sediment and other deposits by means of the transmission of focused, longitudinal oscillations into a liquid, viscous or gaseous, cylindrical conducting medium onto the deposit surface established by means of DASY (three-dimensional scanning system), with control of the pH value of the conducting and solvent medium. The process for removing deposits represents a process for surfaces which have been coated, especially by means of paints or the action of electroplating (electrodeposition). It is intended that the coating should be kept and the solvent used, the thermal, mechanical and electrical added energies be minimised. This requirement is achieved by dividing the process into individual segments which are scanned serially by a three-dimensional scanning system and are processed by a flexible manufacturing system. This manufacturing system guides the sonic transmitter and the cylindrical, liquid, viscous or gaseous conducting medium, following the coordinates predetermined by the scanning system, orthogonally over the deposit surface and generates forced oscillations in the deposits, so that these can be carried away as a result of gravity by the conducting medium flowing off.

Title: Arrangement for measuring, monitoring and representing the surface temperature of a rotating object
Inventor: WETZLER GERD R
IPC: B60C23/20
Filed: 1989-02-11
Abstract: An arrangement for measuring, monitoring and representing the surface temperature of rotating objects such as motor vehicle tyres, rotating drive belts etc. is described. The arrangement consists essentially of an infrared sensor which is displaced parallel to the surface of the tyre etc. by means of a traversing device with displacement sensor. The tyre itself is coupled to an angle sensor which outputs a zero pulse and a specific number of pulses per revolution of the tyre. The pulses supplied by the displacement sensor and the angle sensor are evaluated in a process computer to which means for the optically perceptible representation of the surveyed surface are connected. Furthermore, a light pointer device is provided which transmits a light beam parallel to the measurement beam striking the infrared sensor. This light beam can be pivoted or guided into the axis of the measurement beam or else extend at a fixed distance from the measurement beam. By coupling the displacement sensor pulses and the angle sensor pulses after the measurement run of the tyre has ended, it is possible to use the said light beam to quickly find again a point on the surface of the tyre which is of particular interest because of its temperature so that further measures can be taken.
